Katy Perry recently criticized Lady Gaga for the religious imagery in her controversial “Alejandro” video, and in the new issue of Rolling Stone, she hasn’t changed her tune.

The 25-year-old “California Gurls” singer, whose parents are ministers, launched what seemed like an attack on Gaga in June. Perry tweeted that the “Alejandro” video - in which Gaga, 24, appears dressed as a nun and swallows a rosary - was both blasphemous and “cheap as a comedian telling a fart joke.”

And Perry, who is engaged to equally outrageous British comic Russell Brand, 35, isn’t apologizing for her Twitcism.
